Facrayski
Facrayski is when you're so nuts you could probably get a medal for being weird. It's used when you're doing something so stupid or amazing it makes everyone else look normal.
I tried to ride a skateboard on a trampoline. My friend said, 'You're facrayski!'
I tried to talk to a chicken. The chicken ran away. I said, 'That chicken is facrayski!'
I tried to eat a whole cake in one bite. My sister said, 'You're facrayski!'
